Cinepaint

CinePaint is an open source computer program for painting and retouching bitmap frames of films. It is a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). It enjoyed some success as one of the earliest open source tools developed for feature motion picture visual effects and animation work. The main reason for this adoption over mainline gimp was its support for high bit depths (greater than 8-bits per channel) which can be required for film work. The mainline gimp plans to add (but has not yet added) these features . It is free software under the GNU General Public License.

CinePaint has been in use for many years in feature motion pictures. CinePaint was used by studio Rhythm & Hues for Scooby-Doo, Harry Potter, Cats & Dogs, Dr. Dolittle 2, Little Nicky, Grinch, Sixth Day, Stuart Little, and Planet of the Apes. Sony Pictures Imageworks used CinePaint for Stuart Little II. Hammerhead Productions used it for Showtime and Blue Crush, and will use it for The Fast and the Furious II.

Supported file format:

 BMP,
CIN,
DPX,
EXR,
GIF,
JPEG,
OpenEXR,
PNG,
TIFF,
XCF.

Features of CinePaint:

CinePrint has vast dynamic range : 16-bits per channel (64-bit RGBA)

• that’s more range that can be displayed on a computer monitor,since the computer monitors are 24-bit RGB, and it is important when working with a film.It helps to prevent loss while editing.

Still Photographers and CinePaint

• With 35mm support it helps still photographers too. Still photographers can think of CinePaint as having many more F-stops of range .CinePaint also handles 8-bit, 16-bit linear, and 16-bit float images.
• CinePaint features the support for loss less formats such as TIFF,RLE,Cineon, and EXR, this helps the photographers to preserve the details of their photos without any loss, remember some of these formats are not even supported by Photoshop Gimp or other tools.

Other Main Features

• Frame Manager
• Onion Skinning support
• 16-bit floating point support for HDR and 16-bit colour managed work flow for photographers and printers
• Available in the following platforms: Linux, Mac Native, FreeBSD, NetBSD, Windows XP (Windows version is however broken now, a new version is in progress.)

GIMP

GIMP (GNU Image Manipulation Program) is a free software raster graphics editor. It is primarily employed as an image retouching and editing tool and is freely available in versions tailored for most popular operating systems including Microsoft Windows, Apple Mac OS X and GNU/Linux.

Its Features  :
  

Customizable Interface:

Each task requires a different environment and GIMP allows you to customize the view and behavior the way you like it. Starting from the widget theme, allowing you to change colors, widget spacings and icon sizes to custom tool sets in the toolbox. The interface is modulized into so called docks, allowing you to stack them into tabs or keep them open in their own window. Pressing the tab key will toggle them hidden.
GIMP features a great fullscreen mode allowing you to not only preview your artwork but also do editing work while using the most of your screen estate.

Digital Retouching:

GIMP is ideal for advanced photo retouching techniques. Get rid of unneeded details using the clone tool, or touch up minor details easily with the new healing tool. With the perspective clone tool, it's not difficult to clone objects with perspective in mind just as easily as with the orthogonal clone.

Hardware Support:

GIMP includes a very unique support for various input devices out of the box. Pressure and tilt sensitive tablets, but also a wide range of USB or MIDI controllers. You can bind often-used actions to device events such as rotating a USB wheel or moving a MIDI controller's slider. Change the size, angle or opacity of a brush while you paint, bind your favorite scripts to buttons. Speed up your workflow!

File Formats:

The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP's format capabilities with a plug-in. You can find some rare format support in the GIMP plugin registry.Thanks to the transparent virtual file system, it is possible to load and save files to from remote locations using protocols such as FTP, HTTP or even SMB (MS Windows shares) and SFTP/SSH.
To save disk space, any format can be saved with an archive extension such as ZIP, GZ or BZ2 and GIMP will transparently compress the file without you needing to do any extra steps.
